In this webinar, join HDF Group senior architect John Readey for an introduction to the open source Highly Scalable Data Service (HSDS), REST-based software for reading and writing HDF5 data in the cloud. Developed to make large datasets accessible in a manner that’s both fast and cost-effective, HSDS stores HDF5 files as objects, but provides the functionality traditionally offered by the HDF5 library as accessible by any HTTP client. In this session we’ll cover the client SDKs intertwined with HSDS, the REST VOL and h5pyd, and give a demo of Kita Lab, one of The HDF Group’s commercial services centered around HSDS. Kita Lab is a managed JupyterLab environment with a command line interface, pre-loaded with HSDS, h5pyd, and sample notebooks...

Why do we use HDF5? We moved to HDF5 for our simulation data in 2016 from using our own proprietary file format. HDF5 had been on our radar for some time and we spent a couple of years investigating it and other file formats before deciding which we should switch to. HDF5 met all the criteria we had at the time. Amongst the criteria were: performance in speed and size, an accepted standard for scientific data, being open source, providing additional tools....
